Yamada came to prominence as a teen idol in 2007 following his role in the Japanese television series Tantei Gakuen Q. After launching his music career in 2007 as a member of Hey! Say! JUMP, he released his number one debut solo single, "Mystery Virgin" in 2013. The fact that Yamada was in his teens at the time the single reached number one helped the singer set several records in the Japanese music industry and Yamada achieved wide fame as a solo artist. He became the first teenage male artist in thirty three years to have a number one debut single as well as being one of the only two artists in history to achieve this milestone.
